Get angles of head pose
Hi again,
seems like I'm super stupid, but I don't know how to get the angles of the head pose from the rotation matrix. OpenCV-SolvePnP and then Rodriges give me a 4x4 matrix (rotation + translation) - if I do unterstand this correctly. I thought I can use the roll-angle = atan2(r_{32}, r_{33}) (or atan2(r_{21},r_{22}) when starting to count from 0) and also pitch and yaw to get the angles...
But somehow the values I get do not correspont to the headpose shown in my images. For example there seems to be no big difference between a picture with a frontal head-pose and one with a 45° head-pose (only looking at the angle around the vertical axis...)
Hope someone can help
Thanks
Patricia

Make issue
Hi,
I was just testing out this library for a project on Mac OSX 10.9. When trying to make the examples after running cmake I was getting the following error associated with the file head_pose_estimation.hpp:
error: no type named 'shape_predictor' in namespace 'dlib'
dlib::shape_predictor pose_model;
I have the shape predictor file for dlib to detect the landmarks. Just a bit confused as how to proceed. Any advice?
Thanks!
Solvepnp better output with P3P
Hi,
First of all, thanks for developing this! Works like charm.
I have been messing around with this for a while now and found that P3P method of solvepnp works way better than iterative. Its very stable in profile faces, unlike ITERATIVE, which fluctuates at times, once we turn our head.
Couldn't CMake the project straight away.
Following your installation guide, I got this error

It wasn't mentioned that OpenCV has to be installed. Should I just install it myself? In this case, I will probably pull a request to change the README.md to reflect that. Please let me know.
Other pnp methods and more landmarks?
Thanks for sharing the code, it is really great. A couple of questions. ¿Have you tried other pnp methods implemented in opencv 3 (EPNP, P3P, DLS, UPNP)? ¿Have your tried a different number of landmarks? Thanks.

webcam opens and close in the same time
When I run
ubuntu@ubuntu:~/attention-tracker/build$ ./head_pose_test ../share/shape_predictor_68_face_landmarks.dat
the webcam opens and close and this message is displayed :
init done
opengl support available
Head pose: (0.0385467, 0.0183563, -0.641124)
Processing time for this frame: 91.4945ms
why I can't view the webcam normally ?
Issues with installation/running
I'm able to compile the program successfully, but receive the following error when I try to run the head pose estimation test.
OpenCV Error: Assertion failed (size.width>0 && size.height>0) in imshow, file /tmp/opencv-20160612-56703-1c8n1km/modules/highgui/src/window.cpp, line 261 libc++abi.dylib: terminating with uncaught exception of type cv::Exception: /tmp/opencv-20160612-56703-1c8n1km/modules/highgui/src/window.cpp:261: error: (-215) size.width>0 && size.height>0 in function imshow
I've isolated the error to something in the estimator._debug, as when I try to imshow just the plain frame variable, it works.
I also tried to install gazr to see if a newer version might fix it. I was able to install dlib 18.18 successfully
on its own but couldn't link it to gazr. Here was the output from make-j8

Plotting yaw and roll angles
HI
I have question , I want to draw yaw angles and roll , how can I do something like this image : head pose plot
Using a different set of points
Hi, I'm interested in evaluating how this algorithm performs using a different set of 3D points of the head, for instance using a female head shape to track a female individual. Any advices on that?
Also, how did you manage to get those 3D points? I've looked at the link suggested (wikipedia...) but I could not find anything useful, thanks!

Use code in eclipse project
Hi everyone,
I use Ubuntu 64-bit (in a VM: VirtualBox) and downloaded and installed your code (attention-tracker) as explained in the README and the code sample "head_pose_test" runs fine from console.
My question is: I would like to use this code in an eclipse project (to combine with other code, easy debugging and so on).
I'm a beginner on this field and so I tried many things but can not include it correctly.
In detail: I created a new project, copied the files into src directory, set up for dlib, opencv and ros (in properties).
I have the problem in class "estimated_focus.cpp": Type ' std_msgs::ColorRGBA ' could not be resolved. Google did not help me with this, yet.
Can anyone help me with this please?
Thanks a lot.
Patricia

Installing the Library
I was able to compile the sample files perfectly but I wasn't able to install the library to include it in another project.
I didn't know where to run "make install" exactly. I tried it in several places but with no luck. I am getting the following error: make: *** No rule to make target 'install'. Stop.
So how should I install it and how do I include it exactly?
Thanks in advance.
Delay cv::VideoCapture and 500ms per frame
Hey,
I'm using your code in my eclipse project (Ubuntu 64-bit) and I'm having two problems:
- a delay of 3 seconds using the VideoCapture
- an average speed of 500ms per frame instead of about 1ms (I added the flags -mavx and -msse4 under Project > Properties > C/C++ Build > Settings then on the Tool Settings tab GCC C++ Compiler > Miscellaneous and under Window > Preferences > C/C++ > Build > Settings on the Discovery tab chose CDT GCC Built-in Compiler Settings and add the flags to Command to get compiler specs) I also built in Release mode.
Do you have any idea how I can fix this? Here's the main part of my code (there is of cause a "<" in the includes in my code):
include dlib/image_processing/render_face_detections.h>
include dlib/gui_widgets.h>
include iostream>
include string>
include cmath>
include "head-pose-estimation/headposeestimation.h"
using namespace std;
int main(int argc, char** argv) {
auto estimator = HeadPoseEstimation();
dlib::image_window win;
std::string shapePredictor = argv[1];
estimator.initialize(shapePredictor);
cv::VideoCapture cap(0);
while(!win.is_closed()){
cap >> estimator.matImage; //cv::Mat matImage
dlib::cv_image<dlib::bgr_pixel> cvImage(estimator.matImage);
auto t_start = cv::getTickCount();
estimator.findLandmarks(cvImage);
auto t_end = cv::getTickCount();
cout << "Processing time for this frame: " << (t_end-t_start) / cv::getTickFrequency() * 1000. << "ms" << endl;
win.clear_overlay();
win.set_image(cvImage);
win.add_overlay(render_face_detections(estimator.shapes));
}
}`
Thanks in advance.

resolution of 1920x1080 messes up yaw,pitch,roll axis
My iMac has this resolution, in full screen.
Also, it seems that it has a problem looking up, if you look up the line never points really upwards, or only so much. Maybe because it cant see the face anymore.
installation on Ubuntu 16.04 and ROS kinetic
Whatever the version of OpenCV I use (I tried 2.4.9 and 2.4.13) I obtain this error of compilation:
